Aryna Sabalenka became the first player to successfully defend the Wuhan Open title after a battling victory over American Alison Riske.
Ninth-seed Sabalenka, who beat world number one Ashleigh Barty in semi-finals, needed to show plenty of character to recover and then see off the unseeded American 6-3 3-6 6-1 in a match which lasted almost two hours.
"I can't believe that I defend this title. I couldn't even imagine that I will be able to do this," the Belarusian, the world number 14, said on the WTA Tour website.
"Right now I'm just happy. I can't believe it's happened.
"This means a lot. This year been really tough for everyone."
